CAR-REPLACER.

SPECIFICATION forming part of Letters Patent No. 360.320, dated March 29, 1887.

Application filed December 27, 1886. Serial No. 222,685.

To all whont it may concern:

Be it known that 1, ALEXANDER MoLEoD, of Somerset, Pulaski county, Kentucky, have invented a new and useful Improvement in Gar-Replacers, of which the following is a specification.

My invention relates to an improved construction of frog or skid for replacing cars having flanged wheels upon a railway-track.

In the accompanying drawings, Figure 1 is a side elevation of a portion of a rail-track having one of my replacers attached to it. Fig. 2 is a top view of the same parts, the replacer being shown arranged upon the other side of the rail. Fig. 3 is an end view of the same parts placed in position preparatory to locking the frog in place, the frog being shown on the same side of the rail as in Fig. 2. Fig. 4 is an end view, which represents the frog arranged on the other side and locked.

The construction of my device is such as to enable it to be used with any customary pattern of T- railsuch, for example, as that shown in Fig. 3, or as that shown in Fig. 4.

1 may represent customary wooden cross ties, and 2 may represent a port-ion of a railway-rail. K

3 is ayoke or saddle,approximating the form of an inverted U, Whose middle portion, 4, rests upon, and whose sides 5 and 6 embrace, the top of the rail. The form and dimensions of the side 5 are such as to cause its lower eX- tremity to impinge laterally against the base of the rail on the side nearest to the frog, as shown in Figs. 3 and 4. The side 6 has a transverse slot, 6, which receives a gib, 7, having an orifice, 7, for a key, 9, whose insertion in orifices 10 in the side 6 and the ori (No model.)

fice 7 in the gib 7 operates to fasten the gib, and by so doing to lock the replacer in posio tiou. A screw-threaded pin, 12, is so secured in the side 6 as to occupy a depression, 7, in the top of the gib 7, and to thereby prevent escape of said gib from its slot. Escape of the key 9 is prevented by attaching it by a chain, 5 11, to the gib. The forms and dimensions of the parts are such that the act of driving the key operates to wedge the point of the gib firmly under the head of the rail, and to thus lock the replacer firmly in place.

Rising vertically from the middle of the part 4 of the saddle is a stud, 13, that occupies a corresponding orifice, 14:, in the head or forwardend of my skid, frog, or inclined plane 15, which has the represented arched or convex tread or crown l6, and which has at its tail end downwardly-directed spurs 17, which, having been driven into one of the wooden ties, coact with the described locking devices at the head of the frog to hold it iinmovably to the position in which it has been placed.

I claim as new and of my invention The combination of the frog 15, having the rear spurs, 17, and having the pivoted attachnient 13 to a saddle, 3, one of whose sides, 5, bears against the base of the rail on the side nearest the frog, and the other of whose sides contains the locking-gib 7 and the key 9, substantially as and for the purposes set forth.

In testimony of which invention I hereunto set my hand.

ALEXANDER MOLEOD.
